In this lecture we will learn:
- What is the meaning of Anonymous?
- Anonymous inner class in Java
- Syntax of an anonymous inner class
- Important points related to anonymous class

#1
- Anonymous means something that does not have a name.
- In overriding, to provide a new implementation of a method, we need to create a new class and extend it with the parent class. After extending the class, we override the method.
- We can avoid the overriding and do not need to create a new class for this particular task.
- We can use the inner class concept to give a new implementation of a method.

#2
- We can create a new anonymous inner class after creating an object of a class that contains the method.
- We do not need to use a class keyword with an anonymous inner class.
- It just starts with braces and contains the method and its new implementation.
- Anonymous inner class starts just the creation of an object and ends with the semicolon of that object.
e.g., A obj=new A()
{
public void show()
{
new statement;
}
};

#3
- Anonymous class used in the interface, functional interface, lambda expressions.
- Anonymous inner class can implement only one interface at s time.
- It can either extend a class or implement an interface at a time.
- We do not write a constructor for an anonymous inner class because it does not have any class name.
- An anonymous class has access to the members of its enclosing class.

First time i understood it...great work

[_Kuldeep__Sharma]

You made this concept so easy😊
Thank you sir

[SaiKiranNagulapalli]

For 1 time usage instead of extending class A and method overriding we create a new inner class on fly in main method hence anonymous inner class.

[SuryaSurya-bfmi]

Sir, Is It possible or not, when I want access both main class method along with anonymous class method.

[Alan-fxwr]

Principles aside, isn't possible to just extend the A class by the Demo class, and then provide a new implementation, by simply overriding the show method, of the A class?

[NaveenNT]

Can we have multiple methods inside anonymous class ?

[ChandanG]

It means overite that old design to new

[PremkumarR-tbdp]

is only overriding possible in anonymous class???

[applefanboytelugu]

Hello sir, can we create new methods inside anonymous inner class
